Preheat the oven to 425°F. Line a sheet pan with parchment paper, and set it aside.
Place the ground beef, egg, parmesan cheese, breadcrumbs, garlic powder, onion powder, black pepper, basil, and oregano in a large bowl. Mix well to combine.
Roll 2 tablespoons of the meatball mixture in your hands to form a ball. Place the meatball on the prepared sheet pan, ensuring that it does not touch any other meatballs. Repeat with the remaining meat mixture.
ake for 12-15 minutes at 425°F, or until the meatballs are golden brown, and reach 165°F internal temperature. Remove the pan from the oven and it let cool on the counter while you prepare the crust.
Lightly spray a 14-inch pizza pan with cooking spray. Add one of the pizza dough balls into the center of the pan. Gently stretch it out to be the same size as the pan. If the dough is shrinking back, let the dough rest for 5 minutes and then stretch it out again.
Pierce the dough all over with a fork, and brush ½ tablespoon of olive oil over the dough. Bake the dough for 10 minutes until lightly golden brown.
While the dough is baking, slice the meatballs in half and set them aside.
Remove the dough from the oven.
Spread ½ cup pizza sauce evenly over the dough, leaving a half-inch border along the edge. Top with ¼ of the cheese. Add half of the sliced meatball halves. Top with another ¼ of the cheese. Sprinkle ½ teaspoon dried oregano on top and ¼ teaspoon of garlic powder. Add any other optional toppings you like.
Bake for 10-12 minutes or until the edge of the crust is golden brown and the cheese is melted and slightly browned. Let the pizza sit for 5 minutes before cutting. Repeat all steps with the remaining ingredients to make the second pizza.
